Hyperglycaemia was a risk factor for mortality from severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) and is an independent risk factor for lower respiratory tract infection and poor prognosis. The aim of this retrospective study of 605 patients without previously diagnosed diabetes was to examine the association between fasting blood glucose (FBG) on admission and the 28-day in hospital mortality of COVID-19 patients. Patients with a FBG level of 7.0mmol/l or over had more than double the risk of dying than those with a level of 6.0mmol/l or less. Other risk factors for mortality included age, being male, and severity of pneumonia at admission. Compared with patients whose FBG was 6.0mmol/l or lower at admission, patients with FBG of 7.0 mmol/l and above had a 3.99 times higher risk of in-hospital complications, whilst those with FBG of 6.1–6.9 mmol/l had a 2.61 times higher risk of complications. The authors conclude that glycaemic testing and control are important to all COVID-19 patients even where they have no pre-existing diabetes.
Abstract
AIMS/HYPOTHESIS Hyperglycaemia is associated with an elevated risk of mortality in community-acquired pneumonia, stroke, acute myocardial infarction, trauma and surgery, among other conditions. In this study, we examined the relationship between fasting blood glucose (FBG) and 28-day mortality in coronavirus disease 2019 (COVID-19) patients not previously diagnosed as having diabetes. METHODS We conducted a retrospective study involving all consecutive COVID-19 patients with a definitive 28-day outcome and FBG measurement at admission from 24 January 2020 to 10 February 2020 in two hospitals based in Wuhan, China. Demographic and clinical data, 28-day outcomes, in-hospital complications and CRB-65 scores of COVID-19 patients in the two hospitals were analysed. CRB-65 is an effective measure for assessing the severity of pneumonia and is based on four indicators, i.e. confusion, respiratory rate (>30/min), systolic blood pressure (≤90 mmHg) or diastolic blood pressure (≤60 mmHg), and age (≥65 years). RESULTS Six hundred and five COVID-19 patients were enrolled, including 114 who died in hospital. Multivariable Cox regression analysis showed that age (HR 1.02 [95% CI 1.00, 1.04]), male sex (HR 1.75 [95% CI 1.17, 2.60]), CRB-65 score 1-2 (HR 2.68 [95% CI 1.56, 4.59]), CRB-65 score 3-4 (HR 5.25 [95% CI 2.05, 13.43]) and FBG ≥7.0 mmol/l (HR 2.30 [95% CI 1.49, 3.55]) were independent predictors for 28-day mortality. The OR for 28-day in-hospital complications in those with FBG ≥7.0 mmol/l and 6.1-6.9 mmol/l vs <6.1 mmol/l was 3.99 (95% CI 2.71, 5.88) or 2.61 (95% CI 1.64, 4.41), respectively. CONCLUSIONS/INTERPRETATION FBG ≥7.0 mmol/l at admission is an independent predictor for 28-day mortality in patients with COVID-19 without previous diagnosis of diabetes. Glycaemic testing and control are important to all COVID-19 patients even where they have no pre-existing diabetes, as most COVID-19 patients are prone to glucose metabolic disorders.

Plain language summary
Obesity and Metabolic Syndrome (MetS) in Korea has increased significantly in the last decade and dietary factors, including the consumption of sugar sweetened drinks, is considered one of the key drivers. Soft drinks, soda coffee, fruit juices, sports drinks and sweetened rice drinks are popular beverages in Asia. Consumption of these is a major source of sugar intake for the Korean population. This study analysed data from over 12,112 participants of the Korean National Health and Nutrition Examination Survey (KNHANES) to see if the consumption of sugar sweetened beverages was causally linked to obesity and MetS. Food questionnaires were used in the original study to assess which foods and drinks the participants consumed during a 1-year period. Within the study group the number of participants with obesity was 34.9% and MetS was 26.7% respectively. They found that the participants who regularly consumed >4 sugar sweetened beverages per week consumed more calories on average than those who did not drink these beverages. In men, it was linked to higher blood pressure and blood glucose levels whilst in women it linked to a higher body mass index (BMI), increased waist circumference, and elevated cholesterol. Overall drinking 1 sugar sweetened beverage per day increased the risks of obesity in women by 59% and MetS by 61% whilst in men it increased the prevalence of obesity by 41% and MetS by 7%. Therefore drinking sugar sweetened beverages increases the risk of both obesity and MetS.
Abstract
It is well known that the consumption of sugar-sweetened beverages (SSBs) increases the risk of developing obesity and metabolic syndrome (MetS). However, there are not many studies investigating the link between SSBs and increased incidences of diseases in the Asian population, and in particular, in Korea. We explored the association of SSB consumption with the risk of developing obesity and MetS among Korean adults (12,112 participants from the 2012⁻2016 Korean National Health and Nutrition Examination Survey). We calculated the total SSB consumption frequency by counting each beverage item, including soda beverages, fruit juices, and sweetened rice drinks. Obesity was defined as a body mass index ≥25 kg/m², and MetS was defined using the National Cholesterol Education Program, Adult Treatment Panel III. A survey logistic regression analyses was conducted to examine the association of SSB consumption with obesity and MetS, adjusting for related confounders such as age, energy intake, household income, education, alcohol drinking, smoking status, and physical activity. The SSB consumption was positively associated with an increased risk of the prevalence for obesity (Odd ratio (OR): 1.60; 95% confidence interval (CI): 1.23⁻2.09; p for trend = 0.0009) and MetS (OR: 1.61; 95% CI: 1.20⁻2.16; p for trend = 0.0003) among women. In men, SSB consumption only contributed to a higher prevalence of obesity (OR: 1.38; 95% CI: 1.11⁻1.72; p for trend = 0.0041). In conclusion, increased consumption of SSBs was closely linked with a higher prevalence of obesity and MetS in the Korean population.

Plain language summary
Patients with type 2 diabetes can return to normal blood glucose levels through substantial weight loss. While many studies have addressed this, very few have assessed the effects of adherence to a very-low-energy diet (VLED) on patients’ quality of life. The aim of this study was to evaluate the experiences of adhering to VLED for patients in remission for type 2 diabetes. Fifteen participants were interviewed before and after the 8-week VLED intervention and narratives were analysed. This study identified common barriers, facilitators and strategies used by the participants. Overall, participants found adherence easier than anticipated, and found barriers to be offset by suggested behaviour-regulation strategies. Based on this study, the authors conclude dietary treatment for reversal of type 2 diabetes is acceptable and feasible in motivated patients, and suggest further controlled research be done to confirm the validity and applicability of these findings.
Abstract
AIMS: To evaluate the acceptability of an 8-week very-low-energy diet for remission of Type 2 diabetes, and to identify barriers and facilitators of adherence and behaviour-regulation strategies used by participants in the Counterbalance study. METHODS Eighteen of 30 participants in the Counterbalance study (ISRCTN88634530) took part in semi-structured interviews. Of these, 15 participants were interviewed before and after the 8-week very-low-energy diet intervention. Thematic analysis was used to analyse the narratives. RESULTS The prospect of diabetes remission, considerable weight loss, and long-term health improvement provided participants with substantial initial motivation. This motivation was sustained through the experience of rapid weight loss, improvements in blood glucose levels, social support and increased physical and psychological well-being. Overall, adherence to the very-low-energy diet for 8 weeks was perceived as much easier than anticipated, but required personal effort. Participants addressed challenges by removing food from the environment, planning, avoidance of tempting situations or places, and self-distraction. Weight loss and improvements in blood glucose levels lead to a sense of achievement and improvements in physical and psychological wellbeing. CONCLUSIONS Dietary treatment for reversal of Type 2 diabetes is acceptable and feasible in motivated participants, and the process is perceived as highly gratifying. Research outside of controlled trial settings is needed to gauge the generalisability of these findings.

Plain language summary
As an immune-mediated chronic inflammatory skin condition, psoriasis is associated with obesity, metabolic syndrome, diabetes, and cardiovascular disease. Medications capable of sensitising insulin, such as Metformin and Pioglitazone, have also shown benefits in improving factors associated with metabolic syndrome and psoriasis. This single-centre, parallel-group, randomised, open-label with blinded endpoint evaluated the effects of Metformin with Pioglitazone and placebo in psoriatic patients. Patients with mild-to-moderate psoriasis were randomised to a topical treatment cohort to take 1000 mg metformin daily or 30 mg pioglitazone or placebo groups for 12 weeks. Each participant received a topical ointment containing 5% coal tar during the treatment period. The Metformin and Pioglitazone groups showed significant improvements in psoriasis and metabolic syndrome parameters, such as fasting plasma glucose, total cholesterol, and triglyceride levels, after 12 weeks of treatment. The treatment with metformin resulted in significant improvements in weight, BMI, waist circumference, FPG, triglycerides, and total cholesterol, while the treatment with pioglitazone resulted in significant improvements in FPG, triglycerides, systolic and diastolic blood pressure, cholesterol levels, and LDL cholesterol levels. There was no significant improvement in inflammatory cytokine levels in any group. For further evaluation of the beneficial effects of insulin-sensitising drugs in patients suffering from psoriasis and metabolic syndrome, more robust studies are needed. The study results can be used by healthcare professionals to better understand how insulin-sensitising drugs may decrease the risk of diabetes, cardiovascular disease, and psoriasis in psoriasis patients with metabolic syndrome.
Abstract
BACKGROUND Increased prevalence of metabolic syndrome (MS) is observed in psoriasis. Metformin has shown improvement in cardiovascular risk factors while pioglitazone demonstrated anti proliferative, anti-inflammatory and anti angiogenic effects. Study objective is to evaluate the efficacy and safety of Insulin sensitizers (metformin and pioglitazone) in psoriasis patients with metabolic syndrome (MS). METHODS Single centre, parallel group, randomized, study of metformin, pioglitazone and placebo in psoriasis patients with MS. RESULTS Statistically significant improvement was observed in Psoriasis Area and Severity Index (PASI), Erythema, Scaling and Induration (ESI) and Physician global assessment (PGA) scores in pioglitazone (p values - PASI = 0.001, ESI = 0.002, PGA = 0.008) and metformin groups (p values - PASI = 0.001, ESI = 0.016, PGA = 0.012) as compared to placebo. There was statistically significant difference in percentage of patients achieving 75 % reduction in PASI and ESI scores in metformin (p value - PASI = 0.001, ESI = 0.001) and pioglitazone groups (p vaue - PASI = 0.001, ESI = 0.001). Significant improvement was observed in fasting plasma glucose (FPG) and triglycerides levels in metformin and pioglitazone arms. Significant improvement was noted in weight, BMI, waist circumference, FPG, triglycerides and total cholesterol after 12 weeks of treatment with metformin while pioglitazone showed improvement in FPG, triglyceride levels, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol and LDL cholesterol levels. There was no difference in pattern of adverse drug reaction in three groups. CONCLUSION Insulin sensitizers have shown improvement in the parameters of MS as well as disease severity in psoriasis patients. TRIAL REGISTRATION CTRI Registration Number: CTRI/2011/12/002252 .
